UV absorber-928(C29H35N3O) is a hydroxyphenyl benzotriazole UV absorber specially designed for high performance coating applications. UV absorber-928 provides efficiency to coating and light sensitive substrates due to its characteristic broad band absorption. With excellent solubility and high thermal and environmental performance, UV absorber-928 is particularly suitable for coatings exposed to high temperature curing processes, such as powder and coil coatings, or high environmental stress. This off-white or light yellowish crystalline powder is also suitable for automotive coatings.
UV absorber-928 has a broad absorption characteristic, can effectively protect the coating and other photosensitive materials.
UV absorber-928 has high solubility, high-temperature resistance and environmental durability. Suitable for high-performance coatings, especially for powder coatings and coil continuous coatings, but also for automotive coatings and conventional coatings.
UV absorber-928 in combination with hindered amine light stabilizers, such as HALS-292 or HALS-123, can significantly increase their effectiveness.
UV absorber-928 has broad absorption properties which can effectively protect coating and other photosensitive materials. UV absorber-928 has high solubility, high temperature resistant and good environmental durability and so on. UV absorber-928 is suitable for high performance coatings, especially suitable for powder coating and industrial and automotive coatings. UV absorber-928 can be enhanced when used in combination with a HALS stabilizer such as UV-292 or UV-123.
UV absorber-928 is a new type of hydroxybenzotriazoles, suitable for UV absorbers of high performance coatings. UV absorber-928 has a wide range of absorption characteristics and can effectively protect coatings and other photosensitive materials. At the same time, UV absorber-928 has the characteristics of high solubility, high temperature resistance and good environmental durability. UV absorber-928 is especially suitable for systems that require high temperature curing, such as powder coatings, steel coatings, etc. UV absorber-928 can effectively protect the coating film from light loss, cracking, blistering, delamination and discoloration. UV absorber-928 can be added to varnish, coating and solid color paint. According to our experience, light stabilizer on the surface coating has the maximum protective effect.
